This is a value typical for a large subacute MI, n ormal value 48 hours after myocardial infarction is associated with Post-Infarction Regional Pericarditis ( PIRP ). As already mentioned, this patient could have post-infarction regional pericarditis from a large completed MI. Sinus tachycardia has many potential causes. Hammill SC.

Of course this depends on many factors: 1) duration of occlusion, 2) whether full or near occlusion with zero flow or some flow -- the flow in the artery is the critical factor, measured by "TIMI" flow, 3) presence of collateral circulation and others. Upon questioning patient, he denies having any chest pain or chest tightness of any sort.

Circulation: Arrhythmia and Electrophysiology, Ahead of Print. Postablation chest pain consistent with pericarditis was reduced with colchicine (4% versus 15%; HR, 0.26 [95% CI, 0.09–0.77];P=0.02) BACKGROUND:Inflammation may promote atrial fibrillation (AF) recurrence after catheter ablation. 2.02];P=0.89). 1.99];P=0.55).CONCLUSIONS:Colchicine

60-something with h/o MI and stents presented with chest pain radiating to the back and nausea/vomiting. Pericarditis? A straight ST segment virtually never happens in inferior ST elevation that is NOT due to OMI (normal variant, pericarditis) 4. Time zero What do you think? There is inferior ST elevation.

Recall from this post referencing this study that "reciprocal STD in aVL is highly sensitive for inferior OMI (far better than STEMI criteria) and excludes pericarditis, but is not specific for OMI." See this case: Persistent Chest Pain, an Elevated Troponin, and a Normal ECG. Circulation , 130 (25). At midnight.

A man in his 60's presented after 4 days of chest pain, with some increase of pain on the day of presentation. Exact pain history was difficult to ascertain. When there is MI extending all the way to the epicardium (transmural), that infarcted epicardium is often inflamed (postinfarction regional pericarditis, or PIRP).
